Bolt-free impact-resistant comb plate expansion device
The invention provides a bolt-free impact-resistant comb plate expansion device. Comprising a beam body, a comb plate, a dustproof sliding plate, an elastic support and a water stop mechanism, concrete bodies, steel plates and comb plates are sequentially fixed to the ends of the beam bodies, the comb plates between the adjacent beam bodies are connected in an inserted mode, and the water stopping mechanism is fixed to the bottom of the bridge expansion joint. A step is arranged on the side, away from the concrete body, of the top of the steel plate, and the dustproof sliding plate is fixed to the step of the steel plate and blocks a gap between the two comb plates. The comb plate is fixed to the top end face of the other side of the steel plate, and the step side of the steel plate extends into the middle of the comb plate. The elastic support is arranged between the comb plate and the steel plate, and the dustproof sliding plate wraps the elastic support; the problems that according to a bridge expansion joint full-cantilever structure, a comb plate at the front end is in a suspended state, a vehicle rolls the comb plate, concrete is prone to being broken, a bridge expansion joint semi-cantilever structure and an anchoring assembly penetrate into the lower portion of the comb plate, and a dustproof plate cannot be installed are solved.
本发明提供了一种无螺栓抗冲击梳形板伸缩装置；包括梁体、梳齿板、防尘滑板、弹性支承以及止水机构；梁体端部依次固定有混凝土体、钢板以及梳齿板，相邻梁体之间的梳齿板相互插接，止水机构固定在桥梁伸缩缝底部；钢板顶部远离混凝土体一侧开设有阶梯，防尘滑板固定在钢板阶梯处，防尘滑板挡住两梳齿板之间的间隙；梳齿板与钢板另一侧顶端面固定，钢板阶梯一侧伸入梳齿板中部；弹性支承设置在梳齿板与钢板之间，防尘滑板包裹弹性支承；本发明解决了桥梁伸缩缝全悬臂结构，前端的梳齿板处于悬空状态，车辆碾压梳齿板，容易造成混凝土崩坏以及桥梁伸缩缝半悬臂结构，锚固组件深入到梳齿板的下方，无法安装防尘板的问题。
